.SHORT TERM...TODAY THROUGH MONDAY. EXPECT UPPER LEVEL RIDGING
EARLY TODAY BRINGING MOSTLY SUNNY SKIES AND DRY CONDITIONS.
TEMPERATURES WILL REMAIN WELL BELOW NORMAL JUST MAKING 70 DEGREES
IN LOWER ELEVATIONS. A WEAK WAVE WILL MOVE THROUGH LATE THIS
AFTERNOON INTO EARLY EVENING BRINGING LIGHT SHOWERS ACROSS HIGHER
TERRAIN WITH A SLIGHT CHANCE OF THUNDERSTORMS. SUNDAY THE NEXT
WAVE MOVES THROUGH BRINGING BACK PRECIPITATION ACROSS THE AREA.
MONDAY YET ANOTHER WAVE MOVES THROUGH WITH WEAK PRECIPITATION
CHANCES MAINLY OVER HIGHER TERRAIN. EXPECT TEMPERATURES 5 TO 8
DEGREES BELOW NORMAL THROUGH THE PERIOD. WYATT

.LONG TERM...TUESDAY THROUGH FRIDAY. BOTH THE GFS AND ECMWF MODELS
ARE BRINGING IN A SHORT WAVE RIDGE TUESDAY AND WEDNESDAY. EXPECT
WARMER TEMPERATURES AND OVERALL DRY CONDITIONS TUESDAY AND
WEDNESDAY. WEDNESDAY EXPECT THE WARMEST TEMPERATURES RISING TO NEAR
TO SLIGHTLY ABOVE CLIMO. LATE WEDNESDAY INTO THURSDAY THE GFS IS
BRINGING AN UPPER LEVEL LOW OVER THE AREA BRINGING BACK MOIST
CONDITIONS AND MUCH COOLER TEMPERATURES THROUGH THE REMAINDER OF
THE PERIOD. WYATT

&&

.AVIATION...JUST AS THE ONE TROUGH THAT BROUGHT THE HEAVY RAINS AND
CONVECTION LEAVES...ANOTHER MOVES IN FROM THE NORHTWEST AND ROTATES
A TROUGH THROUGH EARLY TONIGHT.  HOWEVER...THIS ONE DOES NOT HAVE
QUITE THE AVAILABLE PRECIPITABLE WATER AND IS NOT AS UNSTABLE.  MOST
OF THE GOOD MOISTURE IN THIS SHORTWAVE IS ABOVE 600MB.  WIND WILL
REMAIN LIGHT AND THERMALLY-DRIVEN. MESSICK

&&

.FIRE WEATHER...STILL A LINGERING THREAT OF THUNDERSTORMS TODAY
UNDER WHAT NOW IS EXPECTED TO BE A VERY SHORT-LIVED UPPER LEVEL
RIDGE.  THE RIDGE SHOULD BREAK DOWN THIS EVENING AND ALLOW A TROUGH
TO ROTATE THROUGH CENTRAL AND EASTERN IDAHO.  MUCH DRIER TROUGH AND
THUS THUNDERSTORM AND SHOWER ACTIVITY WILL BE MORE LIMITED TO
HIGHLANDS AND MOUNTAIN REGIONS AND NOT AS STRONG.  THE UPPER LEVEL
LOW CONTINUES TO LINGER ON SUN AND MAINTAINS THE SHOWER AND
THUNDERSTORM ACTIVITY IN THE HIGHER ELEVATIONS. TONIGHT'S GUIDANCE
HAS DAMPENED THE SHORTWAVE FOR MON...THUS IT IS FASTER MOVING AND
DOES NOT BRING AS MUCH MOISTURE AND MUCH LESS CHANCE OF THUNDERSTORM
ACTIVITY.  THE FOCUS IS NOW ON THE SUN TROUGH.  WEAK ZONAL FLOW FOR
TUE AND WED WITH A SLIGHT CHANCE OF PRECIPITATION...THEN A LARGE LOW
ON THE GFS APPROACHES FOR THU.  HOWEVER THE ECMWF DOES NOT HAVE THIS
AND THUS HIGH DEGREE OF UNCERTAINTY BEYOND THE 4 DAY PERIOD.  MESSICK

&&

.HYDROLOGY...RECENT RAINFALL ALONG WITH ONGOING SNOWMELT WILL
SUSTAIN HIGH FLOWS ON AREA RIVERS AND STREAMS WITH FLOODING
CONTINUING ON THE PORTNEUF...HENRY'S FORK...TETON AND SNAKE
